[PATCH] D20602: Add .rgba syntax extension to ext_vector_type types

[Richard Smith via cfe-commits]

rsmith added a comment.

Looks like this extension was added at some point between 1.1 and 2.1. It would make sense to produce an `ExtWarn` for it if the OpenCL standard version is less than the one that introduced it (whenever that was) -- that would match what we do for extensions in other languages.
